대충 위와 같이 작업하였으나

pending 코드에서 sleep을 줘도 저기서 계속 리소스를 잡아먹다보니

프로그램이 극도로 느려졌다.

 

그래서 다른 것을 찾아봤고 찾은 것이 apscheduler 다.

https://lemontia.tistory.com/508

여기에 잘 나와있으니 참고하시길 

추가된 코드는 

 

from apscheduler.schedulers.background import BackgroundScheduler #pip install apscheduler
from apscheduler.jobstores.base import JobLookupError             #특정 시간이나 일정 간격 실행을 위한 모듈
import time

 

def job(mainWidget):
     print(mainWidget.df)

 

sched.add_job(job, 'cron', second='*/5', timezone='US/Eastern', id="trading",  args=[self.mainWidget])

 

정도 되시겠다.

5초마다 백그라운드로 job 함수를 실행한다.

나는 특정 시간에 작동하기 위해 

 

sched.add_job(job, 'cron', day_of_week='5', hour='19', minute='15', timezone='US/Eastern', id="trading",  args=[self.mainWidget])

 

크론을 이렇게 줄 예정이다.
